The HVI 2K-F6W Series of rugged high input voltage DC-DC converters employ field-proven HVI2500 topology to deliver up to 2000W output power. The units accept a nominal input of 800Vdc with a 700Vdc to 900Vdc operating input range. Regulated output voltage includes 24Vdc, 28Vdc, 36Vdc, 48Vdc, 110V or custom. An optional built-in redundancy diode allows for paralleling and N+1 operation, or back-up battery connection. An output-fail alarm (Form C) and remote shutdown or enable are available on request.

The high input voltage converters are suitable for a broad range of industrial applications that require a rugged, reliable, DC-power supply capable of accepting high input voltage and where size and weight are constraining factors.

To ensure high reliability and long operating life, all critical components on the primary side are designed and tested for corona inception levels that are significantly higher than the operating voltages. The design is verified for 5600Vdc input to output isolation and production level testing is 4300Vdc input to output. The units are equipped with reverse polarity protection, inrush current limiting, output current limiting, short-circuit protection and self-resetting thermal shut-down in the case of insufficient airflow.

The converters are equipped with heavy filtering on the input and output for low noise. The input meets EN 55032 Class A with wide margins (Class B as an option). This ensures that the unit can be used in EMI sensitive environments without additional filtering. The converters comply with the requirements of EN/IEC 61010-1 and related standards. Low component count, large design headroom, and the exclusive use of components with established reliability also contribute to ensuring that the unit delivers many years of trouble free operation.

Cooling is by high quality built-in fans with which draw air into the unit and exhaust at the opposite side. Additional cooling is provided by conduction via the baseplate. All heat generating components are installed on aluminum heatsink blocks that are thermally connected to the base plate. This also ensures exceptional mechanical ruggedness. The converters operation over a 0°C to +50°C temperature range without the need for derating. Wider temperature ranges are available on request. Efficiency is a minimum of 80% at full load depending on input/output configuration.
